All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0023] As Figures 1 - 5As shown in the figure, a abdominal belt for preventing parastomal hernia by dynamic pressure regulation includes an abdominal belt body 1. Two fixing belts 2 are symmetrically fixed on both sides of the abdominal belt body 1. One side of the end of one fixing belt 2 is fixed with a hook surface 10, and a fluff surface 11 which is matched with the hook surface 10 for fixing is fixed on the side wall of the other fixing belt 2. The cooperation of the hook surface 10 and the fluff surface 11 can fix the two fixing belts 2 together, and the tightness of the fixation of the abdominal belt body 1 can be adjusted. A stoma hole 3 is formed on the abdominal belt body 1. A fixing airbag 8 is fixed on the inner side wall of the abdominal belt body 1. The fixing airbag 8 contacts with the abdomen. The fixing airbag 8 is of a net structure, which is convenient for ventilation and improves the comfort of the patient when wearing the abdominal belt. There can be one or more fixing airbags 8. A pressure sensor 9 is embedded on the side of the fixing airbag 8 facing the patient's abdomen for detecting the pressure value between the human body and the abdominal belt. The model of the pressure sensor 9 is SBA-S. An automatic pressure relief valve is embedded on the side wall of the fixing airbag 8. A whistle capable of emitting a prompt sound is installed in the air outlet hole of the automatic hydraulic valve. When the fixing airbag 8 is squeezed to reach the set pressure, the automatic pressure relief valve automatically opens, and the gas in the fixing airbag 8 is discharged and a prompt sound is emitted through the whistle to remind medical staff and patients to pay attention to the usage specifications. An inflation hole is formed on the side wall of the fixing airbag 8 for facilitating the replenishment of gas. A control box 4 is fixed on the front surface of the abdominal belt body 1. A control module 41 and a storage battery 42 which are electrically connected with the pressure sensor 9 are fixed inside the control box 4. The control module 41 selects an STC89C51 single-chip microcomputer. The STC89C51 is an ISP (In System Programming) in-system programmable chip with an 8051 core, with a maximum working clock frequency of 80MHz. It contains 8K Bytes of Flash read-only program memory that can be repeatedly erased 1000 times. The device is compatible with the standard MCS-51 instruction system and the 80C51 pin structure. A general-purpose 8-bit central processor and an ISP Flash storage unit are integrated in the chip, and it has the in-system programmable (ISP) feature. The storage battery 42 selects a rechargeable lithium battery. A charging jack electrically connected with the storage battery 42 is formed on the side wall of the control box 4. A micro air pump 43 electrically connected with the control module 41 and the storage battery 42 is fixed inside the control box 4. The micro air pump 43 is connected with a movable airbag 6 through a connecting air pipe 5. The shape of the movable airbag 6 can automatically change with the human body to fit the human waist. The micro air pump 43 can be used to inflate the movable airbag 6. The connecting air pipe 5 includes a protective sleeve. An inflation pipe and an exhaust pipe are arranged inside the protective sleeve. An exhaust valve 44 electrically connected with the control module 41 and the storage battery 42 is fixed on the exhaust pipe. By controlling the opening and closing of the exhaust valve 44, the air pressure of the movable airbag 6 can be adjusted, and further the pressure between the abdominal belt body 1 and the patient's abdomen can be regulated. A human-computer interaction module 45 electrically connected with the control module 41 and the storage battery 42 is embedded on the front surface of the control box 4. The human-computer interaction module 45 includes control buttons and a display screen. The control buttons are used to issue control instructions.The display screen is used to display information such as battery level and pressure.

[0024] In this embodiment, the movable airbag 6 is composed of a plurality of cylindrical airbags connected together to form a flexible plate-like structure, which is convenient for surrounding the waist and improves the comfort during use.

[0025] In this embodiment, an anti-detachment device 7 for preventing the abdominal belt body 1 from accidentally falling off is fixed at the upper end of the abdominal belt body 1. The anti-detachment device 7 includes a connecting belt 71 fixed on the abdominal belt body 1. There are at least two connecting belts 71. One end of the connecting belt 71 away from the abdominal belt body 1 is fixed with an anti-detachment fixing belt 72. Snap plugs 73 and snap sockets 74 that can be snapped together are respectively fixed at both ends of the anti-detachment fixing belt 72. The length of the anti-detachment fixing belt 72 is adjustable. The anti-detachment fixing belt 72 can be an elastic belt or a nylon woven bag with an adjustment buckle. After the anti-detachment device 7 is fixed, if the connection part of the fixing belt 2 accidentally disconnects, the anti-detachment device 7 can be used to prevent the abdominal belt body 1 from falling off or moving largely, affecting the use and bringing inconvenience to the patient.

[0026] In this embodiment, the length of the connecting belt 71 is adjustable, so as to facilitate adjusting the distance between the abdominal belt body 1 and the anti-detachment fixing belt 72, ensuring that the connecting belt 71 is in a taut state after the anti-detachment fixing belt 72 is fixed well, and playing an anti-detachment role.

[0027] The working principle of the present invention is as follows: During use, align the stoma hole 3 with the patient's stoma, and then use the cooperation of the hook surface 10 and the hair surface 11 to fix the abdominal belt on the patient's waist. Keep the connecting belt 71 taut. After adjusting the length of the anti-detachment fixing belt 72, make the end parts of the anti-detachment fixing belt 72 fixed together after surrounding the patient's waist in a circle. Insert the movable airbag 6 into the gap between the patient's back and the fixing belt 2, and then start the power supply through the human-computer interaction module 45. The control module 41 controls the micro air pump 43 to work to inflate the movable airbag 6 to make it expand, thereby driving the fixing belt 2 to be taut, so that the abdominal belt body 1 can support the patient's abdomen and have a certain pressing force on the abdomen. The pressure sensor 9 detects the pressure between the fixed airbag 8 and the abdomen. When the set value is reached, stop inflating the movable airbag 6. Then when the patient moves or the body position changes, the control module 41 automatically adjusts the inflation and deflation of the movable airbag 6 according to the detection result of the pressure sensor 9 to realize dynamic adjustment of the pressure of the abdominal belt on the abdomen.

[0028] The circuit connection involved in the present invention is a common means adopted by those skilled in the art, and technical inspiration can be obtained through a limited number of experiments, belonging to the widely used prior art.

[0029] The components not described in detail herein are prior art.

[0030] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
